Rock Machine eSTORM 70 TOUR mountain e-bike Gloss Red/Silver/Black is a hardtail e-bike for commuting and leisure riding on paved roads as well as light off-road terrain. It sits in the mid-range category, where the focus is on balancing everyday practicality with sensible motor performance. It’s aimed at riders who want a stable 29er with an integrated battery and a full road-ready equipment package.
The frame is made from heat-treated 6061-T6 aluminum alloy and uses a comfort-oriented geometry for longer rides in the saddle. The hardtail concept is built around easy maintenance and predictable tracking on gravel. Front suspension is handled by an RST Blaze fork with 100 mm of travel to smooth out bumps. The FSA ZS44/ZS56 headset supports precise front-wheel steering under load from a rack and when riding off-road.
Drivetrain: MicroSHIFT Acolyte shifting runs in a 1×8 configuration. A 12–42-tooth cassette is paired with a 38-tooth chainring and a KMC e8S chain.
Brakes: Alhonga HJ-OD07 hydraulic brakes use 160 mm rotors front and rear. Setup and modulation suit everyday use, including wet conditions.
Wheels and tires: The wheels feature Stars J30 rims and Solon hubs, with a quick release at the front. Rubena Cheetah tires in 29×2,1" increase stability on rougher surfaces.
Cockpit: One1 Alloy handlebars are 720 mm wide with a 31.8 mm clamp diameter. A One1 Alloy suspension seatpost (30.9 mm) is complemented by a Selle Royal Vivo saddle and HERRMANS CLIK DD37 grips.
The Sport Drive MD250S mid-drive motor benefits from natural weight distribution and helps maintain traction on climbs. A peak torque of 90 Nm quickens starts and handles steeper gravel pitches. The 100 mm-travel fork and higher-volume tires damp vibrations, so the bike keeps its pace even on broken asphalt. The 29-inch wheels calm the steering at higher speeds and improve roll-over on edges.
The eSTORM 70 TOUR makes sense for riders who alternate between city commuting, cycle paths, and farm roads. It’s a good fit for experienced cyclists who want the simple 1×8 range and an emphasis on practical equipment. In the category of trekking-oriented mountain e-bikes, it stands out with an integrated battery and readiness for year-round use.
